FLASH WINDER.

Application filed February This invention relates to machines forcompacting metal strips, scraps, or flashings of metal so that they maybe handled safely and occupy a minimum amount of space with maximumweight.

In the shaping or forming of metal articles by drop forging, there isusually an is obtained for the space taken up.

excess amount of metal which is subsequently returned to the chargingbox of the furnace for remelting. This metal is frequently shipped aconsiderable distance to the mill, and it is therefore desirable thatthe pieces or scraps be bundled as compactly as possible so that themaximum weight It is apparent that when these scraps are shipped withoutbeing bundled, but in straight form, a considerable space is utilizedwithout material weight. Furthermore in forging some parts, the scrap orflashing produced is particularly sharp pointed and has been founddecidedly dangerous to workmen handling it, inasmuch as the points areso sharp as readily to pierce thru clothing.

Objects of this invention are to overcome the above difficulties; toprovide a simple and efficient machine for compacting flashings or metalscraps occupying but a relatively small space and having no sharp pointsdangerously positioned; to provide a machine for rolling metal scrapsinto a compact coil and thereafter automatically discharging the coilstherefrom; to provide a new and improved process of bundling metalscraps which is decidedly simple and may be embodied in machines ofsuitable construction; and to provide a scrap bundling machine havingthe new and improved features of construction, arrangement and operationhereinafter described.

The invention is shown by way of illustration in the accompanyingdrawings,- in which:

catch the ring on the rod; Fig. 5 is a diagram of the electric controlcircuit for the operating motor; and Fig. 6 is a detail view of the endportion of the trip lever.

The illustrated embodiment of the invention comprises a bed plate 1 uponwhich a machine frame 2 is mounted, and located in the upper portion ofthe frame 2 is a horizontally disposed, axially movable winding shaft3.A hand wheel 4 is connected to one end of the shaft and the opposite endis formed with a transverse slot- 5 of sub stantial depth.

The winding shaft 3 is connected by means of a key 5 to an elongatesleeve 6 rotatably mounted in the frame. The key 5 is slidable in alongitudinally elongate key way 7 in the winding shaft 3 to permit theshaft to move axially concomitant with the rotation thereof. Mounted onthe inner end of the sleeve 6 is a worm wheel 8 which is clutchedthereto as will be hereinafter described. A worm 9 fixed to adrivevshaft 10 meshes with the wheel 8, and the shaft 10 is operativelyconnected to an electric motor 11. It will be readily seen that rotationis imparted to the winding shaft 3 from the drive shaft 10 through theconnections described.

Slidably mounted in the frame below the. winding shaft 3 and in parallelrelationship thereto is a bar 12 supported in bosses 13 on opposite endsof the frame, and this bar is formed with a yoke 14 extending laterallytherefrom and engaging at one end an annular groove in the adjacent endof the winding shaft 3. When the bar 12 is moved horizontally in theframe, the winding shaft 3 is correspondingly moved, and by means of thedriving connection between the shaft and sleeve 6, rotation of the shaftis permitted during this movement. Mounted in the lower part of themachine frame is a rotatable drum 15 fixed to a shaft 16 which issupported in bearings 17. Secured to one end of the shaft 16 is a gear18 meshing with a pinion 19 which is fast to a shaft 20 and on thisshaft is a worm wheel 21 meshing with the worm 9 so that the drivingshaft 10 imparts rotation to the drum 15 and winding shaft 3.

Depending from the bar 12 is an arm 22 having on the lower end a roller24 which extends into a counter sunk cam groove 25 which extends aroundthe drum 15. For purposes of illustration it may be said that the camgroove 25 is divided into two sections, an annular section 26 and aV-shaped section 27. During the rotation of the drum 15, the roller 24remains in the cam groove and when forced into one leg of'the V-shapedgroove 27, the bar 12 is moved horizontally (to the left in Fig. 4), andupon being forced into the other leg of this groove, the bar is moved inthe opposite direction (to the right in Fig. 4). The length of thesection 26 is so chosen that the winding shaft 3 may rotate severaltimes before the roller 24 engages the V-shaped groove.

Metal scraps or fiashings A are fed to the machine thru a guide ortrough 28, and mounted on a bracket 29 adjacent the inner end of thetrough 28 is a roller 39 over which the flashings ride. In this mannerthe metal is delivered to the winding shaft 3, the strips being insertedthrough the slot 5 in the projecting end of the winding shaft.

When the motor 11 is energized, the winding shaft 3 and drum 15 aresimultaneously rotated and the annular section 26 of the cam groovefirst engages the roller 24. With one end of a metal strip A in the slot5 and the remainder resting on the trough 23, it will be apparent thatupon rotation of the winding shaft, this strip is coiled around theouter end thereof. YVhen the roller enters the V-shaped groove and theshaft 3 commences to move horizontally, the coiled strip is forcedagainst the machine frame. {DEC upon further movement of the shaft thecoiled or bundled strip is forced therefrom, the end of the shaft beingtapered so that it will drop off readily. The winding shaft thereafterreturns to normal position as heretofore described with the slotpositioned horizontally to receive another $1 rip or scrap.

As indicated in Fig. 2 the sleeve 6 is clutched to the gear wheel 8 by aspring pressed ball 31 in a groove 32. This provides a drivingconnection between the sleeve and gear wheel which enables the haft 3and sleeve 6 to be turned in one direction by the hand wheel 4 toposition the slot 5 horizontally in the event it does not stop in theproper feeding position.

A remote control mechanism is employed for starting and stopping the eitric motor 11 and for this purpose a starting contact 33 is supported bythe machine frame and a starting contact 34 connected to one end of aspring arm 35 is engageabie with a contact 33. The portion of the arm 35carrying the contact 34 is normally sprung away from the contact 33 andthe contacts 33 and 34 may be termed the starting contacts. The oppositeend of the arm 35 carries a contact 36 which is engageable with acontact 37 carried by the machine frame and the contacts 36 and 37 arenormally held in engagement.

As diagrammatically illustrated in Fig. 5 current is supplied to themotor through the loads 38, 39 and 40 and when the starting contacts 33and 34 are momentarily engaged, current flows through the leads 3S and41, starting contacts, arm 35, stop contacts, lead 42, through anelectromagnet 43, lead 44 to the main line 40. The current passingthrough the magnet 43 draws the armature thereagainst and the armature45 is connected in a suitable manner to switches 46, 38, 39 and 40 whichmove corresponding- 1y to the armature.

After the starting contacts 33 and 34 have been momentarily engaged theyare sepa rated by action of the spring arm 35 so that thereafter currentflows from the supply line 38 through a portion of the lead 41, throughlead 47, switch 46, lead 48, spring arm 35, stop contacts 36 and 37,lead 42, electromagnet 43, lead 44 and to the line 40. In this positionthe switches 38% 39 and 40 bridge the gap in the motor lines 38, 39 and49 thereby energizing the electric motor 11.

From the above it will be seen that current will be supplied to themotor so long as the stop contacts 36 and 37 are in engagement, but assoon as they are disengaged the electron'iagnet 43 becomes deenergizedand suitable spring means may be employed for moving the armature 45 andassociated switches to the normal position indicated in Fig. 5.

Manually operated means are employed for moving the contact elements and34 into engagement with each other to start the motor, and automaticmeans are also provided for separating the stop contact elements 36 and37 for shutting off the motor after a predetermined movement of theparts. In order manually to move the contact elements 33 and 34 intoengagement, a hand operated lever 49 is pivoted intermediate its ends at50 to the machine frame and is connected at its lower end to a horizontally slidable rod 51 supported in bearing members 52 and 53 atopposite end portions thereof. The upper portion of the lever 49 isformed with a laterally extending arm 54 which normally engages theupper surface of the spring arm 35 in the region of the contact element34.

Fixed to and rotatable with the main driving shaft 10 is a brake drum 55and encircling the drum 55 is a brake band 56, one end of which issecured to the rod 51 and the opposite end of which is fixed to thebearing member 52. It will be seen that clockwise movement of the lever49 moves the contact. element 44 into engagement with the contact til]element 83, the brake band 56 being released from the drum by thehorizontal movement of the rod 51.

Fixed to the opposite end portions of the rod 51 is an annular member 57winch is engageable by a pivoted upper latch 58 when the rod 51 is movedto the left by the operhen the bar 12 moves to the left the arm 59 firstengages the inclined surface 61 on the underside of the latch 58 andraises the same thereby releasing the member 57 which is then caught bya lower latch 62 which is pivoted at one end to a horigiontal bar 63.

It will be noted that the upper surface of the latch 62 is formed with araised portion 6% having oppositely inclined portions and when the partsare at rest this raised portlon 6st engages the underside of the arm 59,thereby holding the latch away from the member 57. The latch 62 issnapped into latching relation with the member 57 by a leaf springengaging the underside thereof.

As the bar 12 continues its movement to the left. the arm 57 nextengages the pivoted end portion 66 of a. bell crank trip lever 67, theupper portion of which engages the underside of the spring arm 35 in theregion of the contact element 36. The engagement of the pivoted endportion 66 by the arm 59 moves the portion 66 upwardly and out of theway and the arm 59 continues its travel.

After the arm 59 has reached the limit of its travel to the left itstarts to the right and first engages the pivoted end portion 66 of thetrip lever 67 and continuing its movement causes the trip lever 67 torotate in a countercloclnvise direction, thereby to raise one endportion of the arm 35 to sepa ate the stop contacts 36 and 37. By thismeans the motor 11 is deenergized but sutlicient momentum has beenattained to continue the travel of the bar 12 and winding shaft to itsextreme right hand position.

The arm 59 next moves under the inclined surface 61 on the trip lever 58allowing it to drop downwardly, and shortly thereafter the lower surfaceof the arm 59 engages the raised portion 64- on the latch 62 and camsthis latch out of engagement with the member 57 which is quickly forcedto the right by means of the coil spring which has again been compressedby the movement to the right of the arm 59. This movement of the member57 correspondingly moves the rod 51 and tightens the brake band 56around the drum 55 which operates to stop the rotation of the drivingshaft 10. A stop 68 on the rod 51 engages the bearing member 52 therebyto limit the movement of the rod to the left.
